What is the perception in Europe of consulting in the Middle East?

I will start working for A.T. Kearney in Dubai as a Business Analyst. There are rumours saying that it’s very difficult to transfer back to an MBB in Europe after 5/6 years (that is how much time I want to spend in Dubai). Is it true? How is consulting in Dubai perceived in Europe?

Agreed with others, unless you are a specialist in a topic that is “hot” across regions, transfer will be very hard. 5-6 years in post-MBA you should be a late principal/early partner, so client relationships are so important that can be ignored only if you bring significant, unique expertise that is in demand (e.g. right now block-chain technology :)).

I can't speak for the remaining "BBs", but at least for McK it's exactly the same if you want to move from Dubai to Europe or from somewhere else, as you will need to have a very strong argument for it, as well as great performance - internally, I've never heard of any negative comments on Dubai, only that is an office highly focused on Public Sector (so it's easier for soemone to move to other offices that are simultaneously strong in such practice)
